Detailed Description
As shown in figures 1-3, the monitoring method in the application mainly aims at monitoring various tissue fluids flowing out of wounds, and the exudation amount is an important monitoring index, therefore, the method relates to a tissue fluid container which is provided with liquid top detectors 1-1 and 1-2, each liquid top detector is surrounded by outer covers 21 and 22 under the condition of leaving a certain gap, the middle of the inner layer of a cavity 1 of the tissue fluid container is provided with two partition plates 3, the cavity 1 is provided with a bottom cover 8 and a front cover 6, the front cover 6 is transparent, the outer covers 21 and 22 of the liquid top detectors are provided with a detecting head 10, a shell 11 and a surrounding cavity 12, the liquid top detectors are respectively positioned at two corners of the top of the cavity 1 which are symmetrically distributed along a diagonal line, the gap positions of the outer covers 21 and 22 are respectively upward and downward, when the exudation amount of the exudation fluids is monitored, the device is communicated with a siphon tube of a negative pressure treatment device, the siphon adsorbs the interstitial fluid of patient wound department to cavity 1 gradually, treat the liquid in cavity 1 and fill up the back, two detecting heads all can detect the existence of liquid, the syntropy signal digital-to-analog conversion module release signal this moment, signal digital-to-analog conversion module relays the signal to central processing unit, central processing unit makes the judgement that the signal is full, send full signal to nurse's monitoring platform this moment, the removable cavity of nurse's monitoring platform, further collect, when patient is because painful, sleep stands up or when changing the position of sitting and lying, probably can make the cavity lie flat, liquid probably is detected by detecting head 10 when not filling up simultaneously, because the vacancy position of dustcoat 21 and 22 is up respectively and down, also can only be detected by a detecting head this moment, the wrong report can not appear.
Furthermore, the monitoring method also comprises a central processing unit connected with a timing device, the user sets the alarm filling time in advance according to the size of the wound and the actual state of illness of the patient, if a large amount of liquid flows out of the wound of the patient in a short time, the nurse is informed and the attending physician is alarmed at the same time, and the wound is further processed.
Further, the monitoring method also comprises the step that the right front part of the transparent front cover 6 is connected with a visual detection camera, the visual detection camera is connected with a color recognition device and a picture comparison and judgment device, the color recognition device detects the color change of the exudate in real time, the picture comparison and judgment device carries out recognition every 1 second, the color of the picture at 0 second is compared with the color of the picture at 1-10 seconds, according to a preset color difference threshold value X, if the color difference threshold value X is larger than the color difference threshold value X, the exudate in the period of time is proved to have abnormal change, and a central processing unit controls an alarm device to inform medical staff of treatment.
The color recognition device detects the transparent color, yellow or red of the deposition liquid at the right time (usually every 2,5,10 or 20 seconds), and if the color is red, the color indicates that excessive blood (usually more than 20 ml/min according to the size and the etiology of the wound) is left in a short time (usually 2.5.10 or 20 minutes), and the central processor controls the alarm device to inform the medical staff of treatment.
Furthermore, the monitoring method also comprises the steps that a PH test paper is placed in the cavity, the visual detection camera and the color recognition device pay attention to the color change of the PH test paper at the same time, and the condition of the exudate can be further judged according to the relation between the preset color and the wound condition development of the patient.
Further, the visual inspection device and the color recognition device compare the change of the ph test paper color once every 2 seconds.
Furthermore, because the specific gravity of blood is relatively large first, and the specific gravity of tissue fluid is relatively small, so the bottom color is red generally, and the upper color is yellow or transparent, so that the operator can preset the color change trend of the exudate under normal conditions, and then, the visual detection camera and the color recognition device carry out real-time monitoring, and if the color distribution is abnormal when the collection is full, an alarm is given.
Furthermore, the visual inspection camera is used as an auxiliary, and the central processing unit monitors the rising speed of the liquid volume according to the calculation according to the change of each frame of picture.
Further, a scale is provided on the transparent front cover 6.
Furthermore, the monitoring method also comprises seepage liquid blockage monitoring, if the change of the seepage amount is not detected by the visual detection camera and the color recognition device within a certain time (which can be 2.5.10,20 minutes and the like), the central processing unit receives feedback and controls the vibration motor positioned outside the cavity or positioned on the seepage liquid conveying pipe to vibrate so as to prevent the seepage liquid from being blocked by the caked tissues.
The detection method provided by the invention can not only avoid wrong full alarm, but also detect the change of the liquid level and the change of the bad exudate in real time by combining the visual recognition device, thereby observing the change of the patient in real time.
